Okato Akira (Nana Kiyono) is a designer working in a well-known design company. She works very hard and is trusted by her superiors and clients. Compared with the smooth sailing in the workplace, Akira's emotional life seems a little pale and pitiful. Almost all the lovers Akira has met are scumbags, and every relationship ends in failure. Nowadays, Akira has long been Buddhist about marriage and love. One day, at a cocktail party, Akira met a man named Momose Hiiragi (Kentaro Sakaguchi). Momose is an employee of an advertising agency. What Akira didn't expect was that Momose proposed to her just after they met. It turned out that Momose didn't fall in love with Akira at first sight, but just to complete the task of getting married. Although she felt very ashamed of Momose's behavior, under the pressure of reality, Akira agreed to Momose's proposal.
